Batch ID Generation
Is there a simple way to generate batch id (Divide samples into 5 groups) based on ID column in a dataset. For example, I have a dataset with 400 samples related to 30 subjects (Multiple samples per subject). I would like to divide the data set into 5 (this can be any value) batches based on the Subject (not samples), so each batch will have 6 subjects related data.
I attached a sample dataset where "Subject ID" is the ID column.
